Hi there,

I’m using the Firefox Multi-Account Containers extension and would like to remove a site that’s been set to "Always open in [X] container." However, I don’t see a “Manage Site List” option anywhere in the container settings as seen here: https://support.mozilla.org/en-US/kb/containers

Here’s what I’ve tried so far:

   I’ve clicked the Containers icon and selected the gear ⚙️ to edit a container.

   I enabled privacy.userContext.siteAssignments.enabled in about:config and set it to true.

   I restarted Firefox (with session restore on), but still no option appears to view or manage assigned sites.

I’m on Firefox Desktop (Mac), and I’ve confirmed that I’m using the official Multi-Account Containers extension.

Is this a bug, a UI change, or something I’m missing? I’d really prefer not to manually edit the containers.json file if there’s a built-in way to manage these assignments.

Thanks so much for any guidance!

Firefox version Mozilla Firefox 137.0.1 has caused my access to content.clubrunner.ca to stop working. How do I revert to version 137.0?

Ok for some reason any of my browsers tabs are crashing I just do whatever it is whether i search or watch movie and after some time 'Gah! your tab crashed' and it's pretty annoying, my discord happens to restart it self and I've exhausted literally anything from re-installing, deleting caches folders absolutely anything.

I've uploaded my latest 2 crashes and hopefully someone can read it and let m know about anything, Thanks in advance!

I restarted Firefox on my Mac earlier, which I think updated it from 136 to 137. After reopening it, web pages won’t load anymore. They either time out or just load indefinitely without doing anything. I went through the troubleshooting page and tried reinstalling it, which didn’t help. My computer’s firewall is off as well. I’ve tried refreshing it multiple times, and I get a message that Firefox has crashed before it actually refreshes. After that, pages will load normally for a very short amount of time (about 30 seconds) before stopping again. Pages are still loading normally on Chrome and Safari, so it’s only Firefox that’s having an issue. Does anyone have any solutions for what this could be/ways to fix it?

I was trying to go to ssa.gov, today, and hit the button to login. When I did that, I got a 400 page saying: Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

I have done this before, and it worked. To test if it was a problem with the web page or the browser, I did it from another browser (Brave), and it loaded fine. Is Firefox sending a bad request? Is this something you can fix.

I am using Mozilla Firefox for Linux Mint 137.0.1 (64 bit).

I was having an issue with pdfs on firefox; all my pdfs were showing up as black. To fix that, I refreshed firefox, which solved the problem just fine. Unfortunately, once I did all my extensions stopped working. The page looks like this.

For most of my extensions, I can just solve this by getting rid of them and adding them again, but if I do that for onetab I'd lose all my stored tabs. How can I get this back?

The proxy settings just don't apply. I set the settings on the system, all programs work via proxy except Firefox (set to use system proxy settings). If I set the proxy manually in Firefox, the connection still doesn't go through the proxy.

I found that only the very first connection after starting Firefox goes through the proxy, absolutely all subsequent connections do not go through the proxy.

when i go to a site using firefox i get this message:

Secure Connection Failed

When I creat a new bookmarks they are not automatically put in alphabetical order but instead are placed in the ned. Why not put them in order when they are made? Anyway, I tried to use the option that allows me to sort bookmarks alphabetically but nothing happens. This used to work but not now. I am using 137.0.1 (aarch64)

I have attached an image to show what I mean.

When I put my laptop to sleep, websites I am logged into are often logged out when I return. Note that I don't close Firefox. The tabs generally reopen but require login again. Windows 11, Firefox 137.0.1

For example, I put my laptop to sleep for lunch. When I returned, tabs were there, but I was logged out of gmail, Discord, and a website I was logged into.

This seems to happen more frequently recently, but not every time, as far as I know. But this is a relatively new problem, possibly related to a new laptop. Occasionally I get a message that there is trouble restoring my session.

Hello there！ I recently updated Firefox to 137.0.1. But the update doesn't automatically display the status bar when you hover over the bottom of the page. I had to resize Firefox to make it full screen to display the status bar properly. This makes it difficult for me to use Firefox. I'm pretty sure this is due to a version update. This problem occurred after I updated the Firefox browser, during which time my Windows system was not updated. Is there any solution? Or how can I download a previous version of the browser?

My webmail is not loading. https://webmail.everyone.net/#/login It keeps spinning and never loads (so I can see the boxes to put in my u/p).

• I've deleted the cookies and cache but that doesn't solve the problem.
• I always keep current with FF updates.
• The problem is only on my computer. No problem on my husband's computer.
• No problem in Edge or Chrome.

What next?

I use tiling for my windows. After minimizing and then restoring the windows, the tab bar is no longer displayed. If I don't tile the windows, this error doesn't occur. I'm using the latest version of Mint Cinnamon. This error also occurred in debug mode.
